How Do You Know Shrimp Is Cooked?

Grilling the Shrimp

Grilling is a popular method for cooking shrimp fajitas, as it imparts a smoky flavor that complements the marinade.

  1. Preheat the Grill: Heat your grill to medium-high.
  2. Skewer the Shrimp: Thread the marinated shrimp onto skewers. This prevents them from falling through the grates.
  3. Grill: Cook the shrimp for 2-3 minutes on each side until they turn pink and opaque.

Sautéing the Shrimp

If you don’t have a grill, sautéing is an excellent alternative.

  1. Heat a Skillet: Use a large skillet over medium-high heat.
  2. Cook the Shrimp: Add a bit of olive oil to the skillet and cook the shrimp for about 2-3 minutes per side.

Serving the Shrimp Fajitas

Once your shrimp are perfectly cooked, it’s time to assemble your fajitas.

Classic Fajita Toppings

  • Bell Peppers and Onions: Sautéed until soft and slightly charred.
  • Guacamole: For a creamy, rich addition.
  • Sour Cream: Adds a cool, tangy contrast.
  • Pico de Gallo: Fresh tomatoes, onions, cilantro, and lime juice.
  • Cheese: Shredded cheddar or Monterey Jack.

Warm Tortillas

Serve your shrimp fajitas with warm flour or corn tortillas. Heating the tortillas on the grill or in a skillet enhances their flavor and texture.

Tips for Perfect Shrimp Fajitas

Choosing the Right Shrimp
